The parable of the sheep and goats is more than judgment; it reveals the character of the King.  He identifies with the needy, being in total solidarity with them.  God always expected kings and governors, to protect the unprotected, and to help whose who have no help. The King and His ambassadors are one with the hurting.  To be one with the King is also to be one with those with whom the King has chosen to be one.

“Then the righteous will answer Him, ‘Lord, when did we see You hungry, and feed You, or thirsty, and give You something to drink? And when did we see You a stranger, and invite You in, or naked, and clothe You? When did we see You sick, or in prison, and come to You?’ The King will answer and say to them, ‘Truly I say to you, to the extent that you did it to one of these brothers of Mine, even the least of them, you did it to Me’” Matthew 25:37-40 (NASB).
